I dont have any desk top dyno stuff, nore do i know how to use one. So if anyone with one would be so kind as to find out how much H/P my set up make's. Here it go's ( 355 sbc with Speed Pro Hyper .030's and a .125 popup dome sittin .10 in the hole, along with a set of .041 head gasket's to make .050 qwench. A set of World Product S/R torquer's with the 76cc chamber's, the head's had .007 shaved off to clean them up. The C/R should be around 9.5, the cam is the Comp H268 High Energy with a .454 lift and .218 @50, and the manifold is the Edelbrock performer EPS with an Edelbrock 600cfm #1405, and a Mallery HEI distributer. I could use a set of GM Performance .028 head gasket's to drop the qwench down to .038 but im think'in that might be a bit to tight. So if someone would be so kind

I come up with 362hp @ 5500 RPMs & 389 ft. lbs @4000 RPMs, personally, with that combo Id use a Weiand Action+ intake & a 625 CFM carb, like the Road Demon... or if you prefer the Edelbrock carbs, a 1" open spacer might help.

Thanx fellow's for your input. I forgot to menchin that i have a 4 hole 1in, spacer from summit racing, and 362hp dont sound bad at all since it's goin in my 1/2 ton pickup, was gonna shoot for the magnu 270 from Comp for some more sound, but i havent even hered the H268 yet, and if i dont like the Edelbrock after i run it for a while ill problebly shoot for a demon.

a friend of mine has that cam and it sounds good and works pretty well in his mild 330-360 hp small block which is very similar to yours the only major differnces are he used vortec heads and he also has a holley 670 street avenger
